How soon after my purchase can I begin using my membership?

When you purchase a COSI membership, it becomes effective immediately.

As a new benefit to COSI members, COSI is excited to offer digital membership cards, accessible through the updated COSI Mobile App. Your digital COSI Membership card is free, convenient, and environmentally friendly. Digital membership cards have taken the place of physical membership cards and will provide a more streamlined, safe, and touchless check-in experience. Digital Membership cards can also be accessed on multiple devices.
How to access your Digital COSI Membership Card via the COSI Mobile App:

  • Download the COSI App – search "COSI Science" in the Apple App Store or Google Play App Store.
  • Select the "profile" icon
  • Log into your COSI Member Account (using primary email address and password associated with your account)
  • Select "Digital Card" on the Profile page
